Abstract

L'invention concerne un élément de liaison (10) pour une paroi de palplanches comprenant plusieurs palplanches. L'élément de liaison a une étendue longitudinale (L) s'étendant parallèlement à une direction d'enfoncement, et l'élément de liaison a une partie droite (20) qui s'étend dans une direction transversale à l'étendue longitudinale (L) le long d'une ligne droite (G), ladite partie droite ayant une première face interne (21) et une première face externe (22). L'élément de liaison a une partie de liaison (30) pour assurer une liaison entre l'élément de liaison et une palplanche, et la partie de liaison (30) ayant une seconde face interne (31) et une seconde face externe (32), une partie de transition en forme d'arc externe (34) étant disposée entre la première face externe (22) et la seconde face externe (32), la première face externe (22) et la seconde face externe (32) étant disposées sensiblement orthogonalement l'une par rapport à l'autre transversalement à l'étendue longitudinale (L), et une partie de transition en forme d'arc interne (33) étant disposée entre la première face interne (21) et la seconde face interne (31), la première face interne (21) et la seconde face interne (31) formant un angle (x) inférieur à 90°. L'élément de liaison (10) a une largeur (B) transversale à l'étendue longitudinale (L) dans une direction qui est parallèle à la ligne droite (G) et une profondeur (A) qui est orthogonale à la ligne droite (G). La partie de liaison (30) a, dans une direction parallèle à la largeur (B), une étendue de largeur minimale (C) qui est adjacente à la partie de transition (33) et une étendue de largeur maximale (D), l'étendue de largeur maximale (D) étant supérieure à l'étendue de largeur minimale (C) d'un facteur de 3 au plus.
